Why should kitchen, toilet choose aluminium alloy door and do not choose wood door and pvc door?
Why do toilet doors and kitchen doors need aluminum alloy doors instead of wood or pvc door? As we all know, toilets and kitchens are relatively humid places, and wooden doors will be affected by damp and moldy, with serious deformation! Many people propose to use pvc door, so let’s comprehensively analyze the performance and characteristics of aluminum alloy doors and pvc door.
1.Wind pressure resistance and water tightness
Due to the low material strength and rigidity of the pvc window, although the steel lining is strengthened by processing, its wind pressure resistance and water tightness performance are about two grades lower than that of aluminum windows. Moreover, because the steel lining of the plastic-steel window is not connected at the corners of the inner cavity of the profile to form a complete frame system, the plastic welding corner strength of the window frame, the four corners of the window sash, and the welding point is relatively low.
Because the frame and fan components of pvc windows are welded, their air tightness should be slightly better than that of screwed aluminium windows, but aluminum window profiles have higher dimensional accuracy, and the frame and sash are tightly matched, so the two are still in one Level level.
The thermal insulation performance of aluminum windows is not as good as that of pvc windows. The heat consumption is less when taking a bath!
The day lighting performance of pvc windows is worse than that of aluminum windows, and the shading area of single frame members is about 10% larger than that of aluminum windows, and the visual field and decorative effects are poor, which is not conducive to energy saving and consumption reduction of architectural lighting. The kitchen and toilet are originally in the backlight of the apartment type! The lighting performance can not be ignored.
5.Sound insulation performance
The gap sealing level of aluminum windows and pvc windows is basically the same, and their sound insulation performance is basically the same.
The fireproof performance of the flame-retardant PVC plastic steel window is better than that of the combustible wooden window, but it is inferior to the non-combustible aluminum alloy window
7.Lightning protection and static electricity issues
Aluminum alloy is a good electrical conductor, so when it is used as a building’s outer protective structure, effective grounding measures can be used as lightning protection facilities and prevent static electricity.
Pvc windows, as exterior windows of buildings, can only be mainly white, which cannot meet the colorful and colorful exterior wall decoration needs of various buildings.
PVC plastic profiles will age. Under the action of ultraviolet rays, the macromolecular chains of the high-molecular PVC resin will break, causing the surface of the material to lose luster, discoloration and pulverization, and the mechanical properties of the profile are reduced. The aluminum alloy has the function of anti-aging.
10.Deformation and expansion problems
Pvc windows are easily deformed by heat, become brittle when cold, and have poor dimensional and shape stability. It is often necessary to use the rigidity of the glass to prevent the window frame from deforming. The aluminum alloy has the advantages of high temperature resistance and deformation resistance.
Based on the above analysis, we suggest that the kitchen and bathroom should choose aluminum alloy doors instead of wooden doors and pvc doors.
